I have a 94 NG900s with 140k. The instrument cluster been just somewhat randomly blanking out for a second or two for the last few months. Sometimes it happens when going over a small bump. Today it blanked out for a good five minutes untill I stopped and started the car again. Is this usually the symptom of a faulty instrument cluster or is it a bad relay or connection to the cluster somewhere? It seemed to happen more often after I moved the relay box above the clutch cable around to get to the clutch adjuster.
